The revalorization of artichoke (Cynara scolymus L.) by-products is a promising strategy to obtain bioactive compounds with antioxidant properties, supporting circular economy approach. This study compares the efficiency an enzymatic pretreatment followed by microwave-assisted extraction (EMAE), ultrasound-assisted (EUAE), and ultrasound-microwave-assisted (EUMAE) at pilot scale for recovering compounds. Extracts were purified using Diaion® HP20 resin phenolic-rich fractions enhanced activity. results showed that EUAE was most effective technique, achieving total phenolic content (TPC) 210.76 ± 1.40 µmol GAE/g d.w. yield 21.38%. HPLC-MS analysis identified 14 major compounds, including chlorogenic acid isomers (60.73 mg/g d.e.), caffeic (34.29 luteolin rutinoside (103.27 among others, which contribute extracts’ high bioactivity. potential extracts assessed Folin–Ciocalteu (F-C), ABTS, DPPH, FRAP assays. exhibited highest activity values, F-C: 985.33 4.46 d.e., ABTS: 80.46 2.39 TE/g DPPH: 87.03 1.11 FRAP: 184.99 2.52 d.e. purification process further TPC activity, enzyme–ultrasound-assisted extraction—purified extract (EUAE-PE) reaching purity 50.71% F-C value 2981.35 12.16
